I cobbled together a rough list of the UK internet radio stations and then had a look at whether they were on DAB.
Pretty much everything that is on the National DAB service is available via the web too. A small number of the local or specialty stations only have DAB licenses, but I guess that only affects a relatively small group of listeners. Finally, there are those handful of stations that have an FM license only - so no DAB or internet.
The forum won't take a direct lift from Excel, and I haven't time to mess about with the list so apologies in advance that it takes some reading.
What we have here is a Station Name followed by a geographic area if applicable, then a comment: Yes = on DAB, No FM only is self explanatory, and blank means it's either a Scottish / Welsh station or a minor regional / specialist station.
